Oracle10g Grid Computing with RAC
Chapter 6 - Install, Configure and Database Creation

On UNIX

In the case of HP’s Tru64 Unix, TruCluster software is needed. However, when implemented on HPUX platform, one these can be used: MC/Service Guard, MC/Service Guard Extension for RAC and Oracle OSD Clusterware.

HACMP cluster framework is needed when building the Oracle RAC database on IBM’s AIX pSeries RS/6000 servers. However, HACMP is not required when Oracle Files are placed on ASM or GPFS. HACMP is only required when data files are placed on concurrent raw logical volumes (CLVM). We have covered more details on the options available on RS/6000 AIX platform in the later sections.

Please note that as of this writing, Oracle has certified Oracle 10g RAC database mostly for the 64-bit Oracle version. It looks like Oracle is encouraging the use of 64-bit Oracle in preference over 32-bit version.

Interconnect

The cluster interconnect is a private network which is used to transfer cluster traffic, Oracle Resource directory information, and blocks for satisfying queries. There are two components involved in setting up and configuring the cluster interconnect, the physical hardware and the interconnect software. The physical connection between the nodes may be through a simple crossover cable or via a switch or hub.
